Possible, but not likely. Everything was new and clean. You're not the first I heard of with no problems, but others say it may not work. Even the old Rumbleseat data he says to use bigger springs. It could be the lightened flywheel wants to rev up so quick. Just cutting the big blob off the 9" Ford flywheel makes a big difference...I like it.

We'll know when I someday take it apart and measure the springs.
